High-efficiency buffer culture medium for high-yield bacterial cellulose and preparation method of high-efficiency buffer culture medium

Abstract

The invention relates to the technical field of culture medium formulas, in particular to an efficient buffer culture medium for high-yield bacterial cellulose and a preparation method thereof.The prepared culture medium provides a comprehensive and balanced nutrition environment for bacteria through elaborately designed components including inorganic salt, microelements, vitamins and specific carbon sources and nitrogen sources; the optimized component combination is beneficial to promoting growth and reproduction of bacteria, so that the yield of bacterial cellulose is increased; the carbon sources can be selected from straw invert sugar or a molasses-glucose mixture, the two carbon sources are renewable resources and are environment-friendly and economical, the nitrogen sources can be selected from a corn steep liquor supernatant solution or soybean protein, and the nitrogen sources contain rich nitrogen elements, provide other beneficial nutrient substances, are beneficial to growth of bacteria, and can be used for preparing the biological organic fertilizer. Due to the flexibility, the culture medium can be adjusted according to different raw material sources and costs, and the practicability of the culture medium can be improved.
